Slide 2

ChloroplastsO Photosynthesis occurs in chloroplasts. Chloroplasts are found in photosynthetic cells of green plants and algae.O It is an organelle which is bound by a double membrane and has a system of stacked flattened sacs called thylakoids, each stack is called a granum.O The internal fluid also within the membrane is the stroma which contains enzymes along with the thylakoid space involved in photosynthesisO Each thylakoid membrane has a series of photosystems containing chlorophyll: a photosynthetic pigment which traps light energy for use in photosynthesis.O They are found on the palisade cells of a leaf…read more

Slide 5

Parts of the ChloroplastO Thylakoid membrane = A system of interconnected flattened, fluid-filled sacs. Have a number of small molecules in them like proteins including photosynthetic pigments (make the leaf green) and electron carriers which help in the light dependant stagesO Stroma = the fluid surrounding the thylakoid membranes. Contains all the enzymes needed to carry out the light- independent reactions of photosynthesis.…read more

Slide 6

O Thylakoid Space = the fluid within the thylakoid membrance sacs which contain enzymes for photolysis (the splitting of water using light energy to give oxygen, hydrogen ions and electrons. The hydrogen ions are used in the light-dependant reactions)O Granum = a stack of thylakoids joined to one another. Grana (plural) resemble stacks of coins.…read more
